Adisk with mass m = 5.7 kg and radius r = 0.43 m hangs from a rope attached to the ceiling. the disk spins on its axis at a distance r = 1.56 m from the rope and at a frequency f = 20 rev/s (with a direction shown by the arrow).

what is the magnitude of the angular momentum of the spinning disk?

Answer :

Explanation :

It is given that,

Mass, m = 5.7 kg

radius, R = 0.43 m

frequency, f = 20 rev/s

Angular momentum,

I is the moment of inertia of disk,

we know that,

so,

Hence, the magnitude of angular momentum of spinning disk is .

the results is a decrease in air temperature with an increase of altitude.

explanation:

which three statements are true about all alloys?
